Snapshot backup

Hello,

I'm using standard backup on HCI.

I have a primary NAS with HCI sheduled backup policy and secondary NAS, NFS storage, that I use as a sort of offgrid backup.

Periodically I turn on the secondary nas and manually I launch a backup for each VM on the related datastore.

To ensure VM disk consistency I turn off the VM, I execute backup and after I turn on the VM.

During the backup operation is not possible to tur on the VM, so the VM may say off for a long time.

I have another Hypervisor, not SF, for testing purpose. To do the same type of backup I do these steps:

- Turn off VM

- LVM Snaphot on volume with VMs files (that's almost instantaneous)

- Turn on the VM

- Mount in read only the LVM snaphot

- Execute my backup tast

- Unmount and remove LVM snaphot

In this way I can run a long backup task but the VM stay off for a very little more time than a normal reboot.

It will be very nice to have such behavior on HCI.
It could be easy to to:

- Turn off VM

- Take a storage based snapshot from VM details page

- Turn on VM

- Lauch backup task of just taken snaphost

- Remove snaphost when backup task finish

The only feature missing on HCI to do these steps is the possibility to execute a backup of a snapshot.

I'm also using Vinchin Backup & Recovery. It helps make live backup.
